. ALCOHOL-STOVE.

Specification of Letters Patent.

Patented March 3, 1908.

T o all whom it may concern:

Be it known that I, ARTHUR W. SWAN- BERG, a citizen of the UnitedStates, residing at Minneapolis, in the county of Hennepin and State ofMinnesota, have invented certain new and useful Improvements inAlcohol-Stoves, and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

My invention has for its especial object to improve the construction ofalcohol stoves, and to this end it consists of the novel devices andcombinations of devices hereinafter described and defined in the claims.

The invention is illustrated in the accompanying drawings, wherein likecharacters indicate like parts throughout the several views. l

Referring to the drawings, Figure 1 is a view partly in elevation andpartly in vertical section, showing a cooking stove designed inaccordance with my invention and Fig. 2 is a vertical section with someparts left in full, showing a heating stove designed in accordance withmy invention.

Referring first to the construction illustrated in Fig. 1, the numeral 1indicates the body of the stove. Secured to the top of the stove body 1and depending therefrom is a conical combustion chamber 2 which, at oneside, is provided with an eccentric conical or laterally offset wing 3.V The space within the wing 3 communicates with the space within theconical chamber 2 through an opening 4, the adjacent wall of saidchamber 2 being terminated short of the bottom of the said wing 3 toafford the said passage 4. The conical Wall of the combustion chamber 2,above the wing 3, is provided with a multiplicity of quite large airpassages 5.

The numeral 6 indicates an elevated tank which is adapted to contain thealcohol and which is rovided with a delivery pipe 7, the end of whichopens into the pocket formed within the wing 3. The flow of alcoholthrough the delivery pipe 7 may be regulated by means of a valve 8.

The alcohol delivered from the pipe 7 into the bottom of the combustionchamber 2 and into the bottom of the pocket or wing 3, rises above thepassage 4..

It is a well known fact that alcohol when lighted will 'burn from itsupper surface only.

within the combustion chamber 2, but will not spread into the pocket 3.The necessary air to support the combustion of the alcohol will besupplied through the air passages or perforations 5. A griddle, kettleor other article to be heated, may be placed directly over thecombustion chamber 2.

In the heating stove shown in Fig. 2, the conical combustion chamber 2with pocket 3 is employed, and these are rigidly secured in any suitableway within the vertical shell 9. This shell 9 is shown as provided witha perforated llaring base 10, and near its top is perforated at 11.

The numeral 12 indicates deflecting plates secured within the shell 9 toincrease the heating efficiency of the stove.

The numeral 13 indicates a door applied in front of the shell 9.

The numeral 14 indicates a fuel magazine which, as shown, is rigidlysecured to the shell 9 by brackets 15 and in such manner that it isadapted to serve as a hand piece.

A delivery pipe 16 leads from the bottom of the tank or magazine 9 andopens into the tank 3 of the said heating stove. The pipe 16 is providedwith a valve 17.

In Fig. 1, the numeral 18 indicates an annular rim secured within thebody l and spaced apart therefrom, the same being concentrically locatedwith respect to the combustion chamber 2.

In Fig. 2, the numeral 19 indicates a similar annular rim which issecured within the shell 9 and is spaced apart therefrom, being locatedconcentrically with, but below the combustion chamber 2.

The stove above described, while es ecially designed to burn alcoholmay,nevert eless, be found eflicient for burning other liquid fuel or liquidhydro carbon.

What I claim is:
